question

We had a lot of rain here during the early morning hours of Wednesday which caused the Lourens river to overflow and which caused the Somerset West / Strand substation to completely flood. The substation tripped, leaving almost all of Somerset West and Strand without power.

It took Eskom more than 24 hours to restore power to us. They apparently restored power by various means of switching things manually or re-routing power from other substations.

The moment the power came back on on Thursday morning, my 3 x Multiplus II in single phase setup switched off the power and said #11 Grid relay test fault.

I am still getting these faults if i try to switch on Eskom power to the system.

This problem only started the moment they restored Eskom power after the flooding. I am wondering if there is something strange on the Eskom supply, or whether my multiplus II could have been damaged.

I am getting these errors:

"11 Grid relay test fault"

Then if I go into VE.Bus Error 8 / 11 report I see:

Phase L1, device 1 (0) #14 0xe00585

Phase L1, device 2 (3) #87 0xe800705

Phase L1, device 3 (6) #143 0xe00585

Then if I click on the 1st device 1: I get: BF safety test in progress, failing step: 5

Then if I click on the 1st device 2: I get: BF safety test in progress, failing step: 7

Then if I click on the 1st device 3: I get: BF safety test in progress, failing step: 5

Does anyone have a list that says what these errors mean? So failing at step 7 and step 5.

Does anyone have any ideas of what might be the problem?

Thank you
